\IVILLIAM A. IOLLOCK, OF NEW ORLEANS, LOUISIANA, ASSIGNOR TO AMERICAN DELINTING 00., OF TIE PLANT, MISSISSIPPI.

DELINTING-MACHINE.

To all whom it may concern:

Be it known that 1, WILLIAM A. PoLLooK, a citizen of the United States, residing at Few Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Delinting-Machine, of which the fol lowing is a specification.

This invention relates to delinting machines. v

One of the objects of the invention is to provide a plurality of converging abrading members so arranged that lint can be withdrawn through oneof said members, means being provided for forcing seed through the throat formed by said converging members, said throat opening into an enlarged chamber in which the seed is permitted to loosen up or expand, said chamber being also provided with abrading means.

'32. further object of the invention is to provide oppositely acting pressing elements for the seed, and means for abrading the seed between said pressing elements.

A further object of the invention is to provide a series of alternating stationary abrasive surfaces and perforated lint outlet plates, combined with a rotating shaft, carrying means at one end for forcing the seed through the machine, and a series of various or graduated sizes of abrasive wheels arried by the shaft and opposed to the stationary surfaces.

A further object of the invent-ion is to mount upon the rotating shaft a series of agitators so disposed throughout the length of the said shaft, as to agitate the seeds and lint to be removed therefrom so that the abrasive surfaces can act thoroughly thereon.

A still further object of the invention is the provision of a delinting machine provided with alternately disposed stationary circular abrasive surfaces and perforated lint outlet plates or rings, combined with inlet pipes for air disposed with relation to each plate or ring and between the abrasive surfaces and with a main exhaust fan to carry the lint sucked through the perfo rated rings away from the machine.

.Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of Specification of'Letters Patent.

Serial No. 626,000.

the invention herein disclosed can be madewithin the scope of what is claimed without departing from the spirit of the invention. I In the drawings :Figure 1 is a longitudinal central sectional view of the complete machine. Fig. 2 is a section taken on line XX of Fig. 1 looking in the direction of the arrows. Fig. 3 is a vertical section taken on line Y-Y of Fig. 1. Fig. 4 is a view on a larger scale of the seed outlet end of the machine,- with a portion of the machine casing broken away to show the perforated rings and abrasive surface carrying rings. Fig. 5 is a perspective view of one of the stationary abrasive surface carrying rings. Fig. 6 is a detail section through the said ring and abrasive surface. Fig. 7 is a detail view of the seed outlet gate or valve.

Referring to the drawings, the numeral 1 designates the standards or supports for the main cylinder or drum 2 of the machine, whose heads?) and 3, are held tightly upon the ends thereof by means of the tie rods 5.

Mounted within the cylinder and provid ing an annular space therearound, are the alternately disposed stationary rings 6 and perforated lint outlet bands or rings 7, the said rings 6, being provided with the oppositely disposed hooked lugs 6, the lower slotted lug 6 and the parallel. guide strips 4; The lugs are adapted for engagement with the tie rods to be held thereby within the cylinder.

Carried between the flanges 6" of each ring 6, is a ring 8, made of an abrasive material and preferably of carborundum, the inner or seed engaging surface being rounded as at 8.

Journaled in the bearings 9 in each head of the machine, is a shaft 10, which has mounted thereon and rotatable therewith within the faces of the abrasive rings 8, a

series of similar diametered abrasive disks 14, the series nearest the inlet end of the machine being provided with the propeller 12, having the angular blades 13, which receive the seeds to be delinted, and propel or force them through the machine toward the head 3'. The seed to be delinted are fed throughthe spout 17, and fall upon the pro peller 12, and'as the shaft rotates are forced along between the rotating abrasive disks 14, and the stationary rings 8, where such lint that is freed, may be sucked through the perforated plates 7 into the space about the rings 6 and 7, within the drum 2, and out through the spout 19, mounted in the Wall of the drum 2, said spout- 19 being controlled by an exhaust fan, not shown, the seed passing on and finally out of the spout 20. In the further travel of the seed, they encounter the agitator 15, provided with a series of detachable blades 15, having the recesses (z, in their ends so that the seeds will not be crushed or mashed as the said blades rotate in close proximity to the surfaces 8 of the rings 8. On the shaft 10, just beyond the agitator 15, is a series of graduated ab 'asive disks 1%, acting with the surrounding cylinder to form gradually reduced spaced chambers, the smallest disk being of ap proximately the diameter of disks 1%, while the largest one is of a diameter that causes the seeds and lint forced or propelled toward it, to be crowded by its periphery in escaping through the reduced outlet thus formed, the propellers 12 and 12, and the series of abrasive disks B, C, l) and E, repeating this operation until the lint is completely rcmoved from the seed and the delinted or cleaned seed are delivered to the screening valve or pivoted gate 21, at the outlet mouth of the seed'outlet spout 20, at the opposite end of the machine from the inlet 17. At this end of the shaft 10, is mounted a reversing propeller, which assists in packing the seed and lint in a roll within the machine, as it works in opposition to the pro pellers l2, l2, and 12 while the agitators 15, 15" and lo", thoroughly agitate the roll of seed, and lint so that the abrasive surfaces will. act thereon and thoroughly delint and clean the seed before they are permitted to leave the machine through the outlet spent 20, in the worm conveyer 22, to be carried to the grinders and presses.

In order to insure the pro-per removal of the lint as it is rubbed from the seed by the abrasive elements at various points in the machine, the air inlet spouts 18 which are rectangular in cross section, have their ends seated within the parallel guide strips 4, of opposing faces of rings 6, and their mouths in direct contact with the outer faces of the perforated rings 7, at such point. In this way, air is admitted to the machine through the spouts 18 throughout the length thereof, and any lint drawn by the suction fan, not shown, through the perforations of the respective plates or rings 7, will enter the space surrounding the rings 6 and 7, and the spout or flue 19, to be carried away from the machine.

It will be noted that the opposed means for imparting axial impulse to the seed within the chamber, that is the wheel 12, 12, or 12", and the wheel 16, are in reality opposed means imparting a differential. axial impulse to the seed in the chamber of the machine. This action is due to the action of the seed propellers 12, 12 and 12, being slightly greater than the opposed action of the wheel 16; thus slightly compressing the seed during the abrading thereof, but permitting the propulsion thereof toward and against the action of the wheel 16.

The capacity of the machine is regulated entirely by the size of the abrasive disks and rings, and by the various numbers of series thereof mounted upon the shaft and within the cylinder, the main feature being the provision of the graduated series of disks combined with propelling means to propel the seeds to be delinted into abrasive contact with the disks and rings, the graduated series permitting a better crowding thereof within the machine between the disks and rings, and providing a means whereby the lint is removed at various points through the rubbing operation.

By providing the agitators at predetermined places along the shaft and within the rings 6 and 7, the rolled or matted seeds are agitated so that too great matting or crowd ing is prevented, and the operatimi of looscn ing the lint and cleaning the seed is accelerated.

It will be obvious from the foregoing description, taken in connection with the draw ing, that the graduated abrading rings H, in connection with the abradmg rings 8, produce converging abrading surfaces, which in effect constitute an abrading throat. It is also obvious that the annular spaces surrounding the series of abrading disks B and D constitute expansion chambers in which the seed, forced through the converging abrading surfaces, permitted to loosen or expand, so as to prevent matting of the seed. It will also be obvious that the propellers 13,12 and 12 on the one hand and the propeller 16 on the other hand, constitute oppositely acting pressing elements be tween which are located the alu-a ding means.

It is evident that this machine can be used for hulling other seed, that carry no lint, without departing from the spirit of the invention, the fiber and hulls removed from the seed being sucked through the outlet flue, while the seed are discharged through the seed discharge spent 20.
